Everything but the kitchen sink?
When you buy a kitchen sink for your new house, get the biggest one you can find. Make sure it can fit the entire wok inside. I find ceramic basins to be the best (very retro too) but they risk being scratched unlike modern synthetic basins. No matter what size the basin is, it better be slightly concave so water and goop always flow into the exit hole. My current sink is perfectly flat, so I spend too much time cleaning it.
